Boost regex asterisk issue

[ged12345]

Hey all,

I've been playing around with the boost filesystem and regex libraries. I'm coming across a really annoying bug.

This page:

http://rosettacode.org/wiki/Walk_a_directory/Recursively

Has how to walk through directories in a recursive fashion. You search down to boost and it implements a regex variable:

boost::regex pattern("a.*");

I can add this code to my project fine and it compiles.

If, however. I declare this:

boost::regex pattern("*.mpeg");

the program will build but not run.

This is the error message:

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

I may be messing up the way regular expressions are used but I just want to
search for filename extensions in a program. I thought regular expressions would be great for this purpose.

Anyway, any help would be appreciated.

catch that exception and print its .what() string so that you know what's going on.

And yes, that is not a valid regular expression. Asterisk doesn't mean "any number of any characters", it means "match the previous atom zero or more times"
